    • The invention pertains to a process for preparing an activated catalyst, to the activated catalyst composition and the use thereof in the conversion of hydrocarbon feedstocks, such as isomerisation. The catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminium compound on an alumina carrier is activated by contacting it with an inert gas in the absence of hydrogen at a temperature above 400 DEG C, wherein at least when the hydrocarbon-susbtituted aluminium compound is a non-halide hydrocarbon-substituted aluminium compound, the catalyst composition is contacted with a halogen-containing gas either prior to the treatment with the inert gas or during the treatment with the inert gas, and subsequently cooling down the activated catalyst to ambient temperature in an inert gas optionally containing hydrogen or containing, at a temperature below 400 DEG C, a halogen-containing gas; or if a halogen-containing gas is present during the treatment with the inert gas, alternatively cooling down in a mixture of an inert gas, a halogen-containing gas, and, optionally, hydrogen.
    • 本发明涉及制备活化催化剂,活化催化剂组合物的方法及其在烃原料转化如异构化中的应用。 在氧化铝载体上包含VIII族贵金属和烃取代的铝化合物的催化剂组合物通过在高于400℃的温度下在不存在氢的情况下与惰性气体接触来活化,其中至少当烃 - 取代 铝化合物是非卤化物烃取代的铝化合物,催化剂组合物在用惰性气体处理之前或在用惰性气体处理期间与含卤素气体接触,随后将活化的催化剂冷却至 在惰性气体中,任选地含有氢气或在低于400℃的温度下含有含卤素的气体; 或者在用惰性气体处理期间存在含卤素的气体,或者在惰性气体,含卤素气体和任选的氢气的混合物中冷却。
